ABSTRACT:
The polygonal chart drawing processing device inputs information including the number N of evaluation items, the length M of an evaluation axis, evaluation items and values for the drawing object from the radar chart drawing processing device. The device generates base graphics (e.g. isosceles triangle) as many as the number of evaluation items, then, by obtaining the length L of an isosceles side of the similar figure to the base graphic, generates an item-value-corresponding graphic having a vertical angle being 2π/N and an area representing an item value of the corresponding evaluation item. The device then draws a polygonal chart which consists of all the item-value-corresponding graphics arranged in a radial pattern with the indicator axis of a radar chart being placed over a center line of the corresponding item-value-corresponding graphic and the vertical angle of the item-value-corresponding graphic being placed over the center point.
